Some sites are pretty doubtful, all right. And I can't see any Hebrew elements in Amaris ... but Mrs
Claire and
Andy will know better.
In classical Latin, Amaris means "You are loved", which is a very positive name for a child ... the Romans would never have used it as a name, of course, but they wouldn't have used
Amanda either. It could also have an etymological connection with vinegar, but let us be cheerful and optimistic!
